## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-audit-agentdiet-dev-hackernews-developer-ecosystem-real-time-4b5f49d5 -d '<json body>'
```

Example prompt: What's the current developer sentiment around Bun on HackerNews — is it trending positively, how fast is it moving on the front page, and what are developers actually saying about it?

## When to prefer this

Use this endpoint when you specifically need real-time developer community sentiment from HackerNews — ideal for gauging technical credibility, startup buzz, or framework adoption health among software engineers. Prefer this over general web search when you want curated developer opinion rather than marketing content, and when front-page velocity or discussion thread depth matters.

## Known failure modes

- Empty or whitespace query returns validation error
- Very niche or obscure topic may yield low discussion volume or sparse results
- HackerNews Algolia API downtime could cause upstream fetch failures
- Ambiguous query keywords may return mixed or irrelevant sentiment data
- Rate limiting or payment failure (x402) blocks the request
